Stereoisomerism in transition element complexes. Describe the types of stereoisomerism shown by complexes, including those associated with bidentate ligands: a. geometrical (cis-trans) isomerism, e.g. square planar such as [Pt(NH3)2,Cl2] and octahedral such as [Co(NH3)4(H2O)2]2+ and [Ni(H2NCH2CH2NH2)2(H2O)2] b. Optical isomerism, e.g. [Ni(H2NCH2CH2NH2)3]2+ and [Ni(H2NCH2CH2NH2)2(H2O)2]2+.
